Product Details

Whether you're replacing an existing air conditioner or working on a project that requires a more permanent installation, WallMaster is a perfect fit for existing 27" sleeves. Once installed, there is no discernible gap between the unit and the sleeve, for a clean, finished appearance and minimal intrusion of outdoor air. Built with the best commercial-grade materials and components, WallMaster is durable yet quiet. Its solid-side sleeve assures maximum performance in thicker wall applications and gives you multiple installation options. Plus, the Baffle Adapter Kit expands the depth of sleeves that can accommodate WallMaster. Choose from cooling-only, cooling with electric heat or a heat pump, including ENERGY STAR® qualified models. All WallMasters come with a wireless remote plus convenient top-mount controls, a 24-hour programmable timer, an energy-efficient MoneySaver® setting and many other premium features.

Features

Commercial-grade components, superior construction
WallMaster is constructed with quality materials and rugged components that contribute to its longevity and quiet performance.

Designed specifically for thicker wall installations
Unlike solid-side thru-the-wall air conditioners, window air conditioners have side vents. Covering an air conditioner's side air vents (as shown to the right) can restrict air flow, diminish performance and potentially void your warranty so we strongly advise against it. Our solid-side sleeve has no side vents. You can install it through walls up to 15 5/16" deep without compromising performance.

Flexible options
WallMaster fits perfectly with any 27"Wx16 ¾"Hx16 ¾"D sleeve, including Friedrich's WSD sleeve and Fedders' A sleeve. It also can be installed in Fedders' 19 ¾" B sleeve with the available Baffle Adapter Kit (BAK). The unit can be mounted flush with an exterior wall or closer to the interior wall for a slimmer indoor profile. And the optional architectural grille enhances the unit's exterior appearance.

Models for a variety of commercial applications WallMaster has models for any climate. Choose cooling-only, cooling plus electric heat, or a heat pump.

Cooling with electric heat: Provides air conditioning and electric heat in a single unit. Ideal in regions with colder winter temperatures.

Heat pump: Provides air conditioning and high-efficiency heating in a single unit. At peak efficiency heat pumps use 1/3 of the electricity used by an electric heat unit. Heat pumps are an excellent choice in regions where the average winter temperature remains above 45° F.

What's the difference between electric heat and a heat pump?
There are important operational differences that can impact your energy bill. Consider the average winter temperature in your area and consult your energy supplier about costs before you buy.

Electric heat, also known as electric resistance heat, is created when an element inside the unit is heated by an electric current. A fan sends the heat directly from the unit into the room; your hair dryer works the same way. Electric heat can be more comfortable in climates where the average winter temperature is below 45° F.

A heat pump is an air conditioner that can run in reverse to provide heat. In air conditioning mode, it removes heat from the indoor air and expels it outside. In heating mode, it extracts heat from the outdoor air and uses it to heat your indoor space. At peak efficiency, heat pumps use 1/3 of the electricity used by an electric heat unit. However, heat pumps heat most comfortably and efficiently when the average winter temperature stays above 45° F. They are not well suited to, or as energy efficient in, colder climates.
